Event-triggered network-based control of discrete-time singular systems

Abstract

This paper is concerned with the problem of event-triggered control for a networked discrete-time singular system. A novel event-triggered networked control scheme is proposed to save the limited network communication bandwidth. By using a delay system approach, a unified model of event-triggered control system is established. A new criterion is proposed in terms of strict linear matrix inequality (LMI) by using Lyapunov functional method, which guarantees the admissibility of the discrete-time networked singular system without resorting to decomposing the system matrices. A state feedback controller is then designed based on this criterion. Finally, a numerical example is provided to illustrate the effectiveness of the proposed method.
